How It Works: Mode of Action
Anchor works by starving the weed. It is a Photosystem II inhibitor, which means it blocks the plant's ability to process sunlight into energy.
- Uptake: The herbicide is absorbed rapidly through the roots (from soil) and leaves.
- Transport: It travels up the plant's water system (xylem) to reach the leaves.
- Shutdown: It blocks electron transport in the chloroplasts. The weed turns yellow (chlorosis), dries up, and dies due to energy starvation and oxidative stress.
Target Crops & Pests
| Crop | Target Pest(s) |
|---|---|
| Sugarcane | Cyperus (Motha), Cynodon (Doob grass), Parthenium, Convolvulus (Bindweed) |

| Potato | Chenopodium (Bathua), Trianthema (Carpet weed) |
Dosage & Application Guide
The Golden Rule: Always follow the "Dose per Acre" for accurate results. Note: As this is a powder, doses are in grams (g).
Dosage per Acre, Litre, & Pre-Harvest Interval (PHI)
| Crop | Dose (g / Acre) | Water (L / Acre) | Dose (g / Litre) | PHI (Days) |
|---|---|---|---|---|
| Sugarcane | 400 - 600 g | 200 - 300 L | 2 - 3 g | 120 |
| Potato | 300 - 400 g | 200 L | 1.5 - 2 g | 30 |
| Wheat | 100 - 120 g | 200 L | 0.5 - 0.6 g | 90 |
*PHI = Pre-Harvest Interval: The minimum number of days to wait between the last spray and harvesting.
How to Apply: Best Practices
- Timing: Wheat: 30-35 days after sowing (after 1st irrigation). Sugarcane/Potato: Pre-emergence (3-4 days after planting) or Early Post-emergence.
- Mixing: Do not dump powder directly into the tank. Mix a little water with the powder to make a smooth "slurry" first, then pour that into the spray tank.
- Coverage: Use a Knapsack sprayer with a Flat Fan or Flood Jet nozzle. Ensure uniform soil coverage for pre-emergence results.
- Safety: Always wear PPE (gloves, mask, goggles). Wash hands thoroughly after use.
Frequently Asked Questions
1. Can I use Anchor on sandy soil for Wheat?
No. Do not use Anchor on sandy soils or soils with low organic matter. The chemical can leach down to the roots and damage the crop.
2. Is Anchor safe for all Potato varieties?
No. It is safe for Kufri Jyoti and Kufri Chandramukhi. However, do not use it on Red Skin varieties like Kufri Sindhuri as it will burn the crop.
3. Can I mix Anchor with Insecticides or Urea?
No. Never tank mix Anchor with Urea, insecticides (like Chlorpyrifos), or growth regulators. This stops the crop from detoxifying the chemical and causes severe leaf burn.
4. Does rain affect the spray?
For post-emergence spray (on leaves), you need at least 6 hours without rain. For pre-emergence (on soil), light rain can actually help, but heavy rain might wash it away.
5. What is the shelf life of the product?
When stored in a cool, dry place in its original sealed packaging, Anchor remains stable for at least 2 years.
